preparation example Construction

[0018] The preparation method of the moisture-absorbing quick-drying cotton fabric of two-way structure of the present invention comprises the following steps:

[0019] (1) Mix polyethylene emulsion, penetrating agent, sulfuric acid and water to obtain the first finishing solution, pad the cotton fabric with the first finishing solution, wind up, and stack at 40-60°C for 5-48 hours , and then washed and dried;

[0020] (2) Mixing the hydrophilic softener and water to obtain a second finishing solution, padding the cotton fabric obtained after the treatment in step (1) with the second finishing solution, and then drying and baking.

[0021] In the method of the present invention, in the first finishing liquid, the concentration of the polyethylene emulsion can be 30-80g / L, preferably 40-60g / L; the concentration of the penetrant can be 10 -40g / L, preferably 20-30g / L; the concentration of the sulfuric acid is 2-6g / L, preferably 3-5g / L.

[0022] In the method of the present inve...

Embodiment 1

[0031] (1) Polyethylene emulsion, penetrant NR, sulfuric acid and water are mixed to prepare the first finishing solution, wherein the concentration of polyethylene emulsion is 40g / L, the concentration of penetrant NR is 30g / L, and the concentration of sulfuric acid It is 4g / L. The cotton fabric was soaked twice and rubbed with the first finishing liquid, the squeeze rate was controlled to 60%, coiled, stacked at 40° C. for 48 hours, then washed with water and dried.

[0032] (2) Add the hydrophilic softener SYNICO-6811 into water to prepare the second finishing liquid, wherein the concentration of the hydrophilic softener SYNICO-6811 is 50 g / L. Then, it was dried at 85° C. for 2 minutes, and then baked at 150° C. for 3 minutes to obtain finished cotton fabric A1.

Embodiment 2

[0034] (1) Polyethylene emulsion, penetrant NR, sulfuric acid and water are mixed to prepare the first finishing solution, wherein the concentration of polyethylene emulsion is 60g / L, the concentration of penetrant NR is 20g / L, and the concentration of sulfuric acid It is 5g / L. The cotton fabric was soaked twice and rubbed with the first finishing liquid, the squeeze rate was controlled to 70%, coiled, stacked at 60° C. for 12 hours, then washed with water and dried.

[0035] (2) Add the hydrophilic softener SYNICO-6811 into water to prepare the second finishing liquid, wherein the concentration of the hydrophilic softener SYNICO-6811 is 40 g / L. Then, it was dried at 90° C. for 1 minute, and then baked at 140° C. for 5 minutes to obtain finished cotton fabric A2.

Abstract

The invention relates to the technical field of textile printing and dyeing, and discloses a preparation method of a bi-directional moisture absorption quick-dry cotton fabric. The method includes thesteps: (1) mixing polyethylene emulsion, penetrating agents, sulfuric acid and water to obtain first finishing liquor, soaking the cotton fabric into the first finishing liquor, rolling the cotton fabric, stacking the cotton fabric for 5-48 hours at the temperature of 40-60 DEG C, and washing and drying the cotton fabric; (2) mixing hydrophilic softeners and water to obtain second finishing liquor, soaking the cotton fabric treated in the step (1) into the second finishing liquor, and drying and baking the cotton fabric. The cotton fabric finished by the method has good moisture absorption quick-dry performance and hydrophilicity.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a method for preparing a bidirectional structure moisture-absorbing quick-drying cotton fabric. Background technique [0002] In recent years, with the improvement of the quality of life, people's pursuit of fitness and shaping has become higher and higher, and more and more athletes are engaged in outdoor activities. Sports enthusiasts prefer natural fiber clothing, especially pure cotton fabrics, which are soft Comfortable, natural and eco-friendly, easy care and long-lasting durability are the favorites. However, when the human body sweats a lot, the cotton fiber will swell due to moisture absorption, the fiber cross section will increase by 40-50%, the fabric will become tight, and the pores will be blocked, hindering the heat exchange between the microclimate between the skin and the clothing and the external environment. Exchange and moisture exchange, ...
